4-Way Stop Rules: Who Goes First, Every Time

Four cars, four stop signs, and nobody moves. Then two of them go at once. The all-way stop is one of the most common intersections in America and one of the most misunderstood, which is exactly why permit tests love it. The good news: 4-way stop rules boil down to a short priority list, and once you can apply it to a few scenarios, you'll never freeze at one again.

How 4-way stop rules work

Look under the octagon. At an all-way stop, a small plaque reads "ALL WAY" (or, on older signs, "4-WAY" or "3-WAY"). The federal Manual on Uniform Traffic Control Devices sets that design, and states write the right-of-way law that goes with it. The details vary slightly from state to state, but the order of priority is the same almost everywhere:

1. Everyone stops completely. Behind the stop line, or before the crosswalk, or where you can see, in that order.
2. First to stop goes first. Arrival order beats everything else.
3. Tie? Yield to the driver on your right.
4. Facing each other at the same time? Straight and right turns go before a left turn.
5. Pedestrians in a crosswalk always come first.

Think of these as a ladder. You only climb to the next rule when the one above doesn't settle it.

Rule 1: first to stop, first to go

The car that comes to a full stop first gets to proceed first. Not the car that arrived first while rolling, and not the biggest vehicle. A full stop means the wheels stop turning, not a slow roll.

Scenario 1: staggered arrivals. You stop at the north side. A second later, a pickup stops on the east side, then a sedan on the south side. You go, then the pickup, then the sedan. Each driver keeps a mental queue of who was already waiting when they arrived.

Rule 2: tie goes to the driver on the right

When two cars stop at the same moment on cross streets, the driver on the left yields to the driver on the right.

Scenario 2: simultaneous arrival at right angles. You're heading north. A car on the east side stops at the same instant. That car is on your right, so it goes first. If the car had been on the west side, it would be on your left and you'd go first.

Scenario 3: three cars at once. Cars stop together on three approaches, leaving one side empty. Find the driver whose right-hand approach is empty: nobody is on their right, so they go first. The queue then rolls around the intersection, each driver going once the approach on their right clears. Two drivers facing each other who are both going straight can usually move together. In practice, this is where eye contact and a wave matter. Rules give an order, but no driver ever has the right of way to cause a crash. Someone has to clearly yield. If it's ambiguous, let it be you.

Four at once creates a perfect loop where everyone has someone on their right. There's no legal tie-breaker. One driver must make it clear they're waiting, usually with a hand signal, and the queue resolves from there.

Turning left at a 4-way stop

Scenario 4: head-on arrivals, one turning left. You and an oncoming car stop at the same time, facing each other. You want to turn left; they're going straight. Because your paths cross, you yield. Straight-through traffic and right turns go before a left turn when two drivers face each other.

If both of you are going straight, or both turning right, your paths don't conflict, so you can go together. If you both want to turn left, you can usually turn at the same time, passing in front of each other (driver's side to driver's side), as long as the intersection is wide enough.

Signal early. At an all-way stop, your turn signal is how everyone else figures out whether your path crosses theirs. A driver who sits there without a signal forces everyone to guess.

Pedestrians and cyclists at all-way stops

Scenario 5: the walker who appears after you stop. You've stopped, you're next in line, and a person steps into the crosswalk in front of you. They have priority. Wait until they've cleared your lane and the next lane, then take your turn.

A few more people-related rules:

• Cyclists are vehicles in most states. A bicycle that stops before you goes before you. Give a bike the same queue spot you'd give a car, and don't squeeze past one in the intersection.
• Right turners, watch the crosswalk on the street you're turning onto. That's where people get hit, because the driver is looking left for cars.
• Kids and dogs don't follow the queue. Scan corners before you go.

T-shaped and three-way stops

Not every all-way stop has four legs. At a T intersection with stop signs on all three approaches, the same ladder applies: first to stop goes first, then the driver on the right.

The trap is the driver on the stem of the T. They must turn either right or left, so they often have the car on their right coming straight across. When the stem driver and a through driver arrive at once, the right-hand rule usually settles it, but if the stem driver is turning left across the through driver's path, the through driver goes.

Where only the stem of the T has a stop sign and the through road doesn't, it's not an all-way stop at all. The stem driver yields to everyone. Check that plaque.

When a light goes out: treat it as a 4-way stop

During a power outage, a dark traffic signal is treated as an all-way stop in most states. Everyone stops, and then the first-to-stop and right-hand rules apply. If a police officer or flagger is directing traffic, their signals override everything else.

A flashing red signal works the same way as a stop sign. A flashing yellow means slow down and proceed with caution; you don't have to stop unless something is in your way.

Common mistakes that cost points

These show up on road tests and in real-life fender benders:

• Rolling stops. On a road test, failing to come to a full stop at a stop sign is frequently treated as a serious error. Our post on automatic fails on the driving test lists the others.
• Waving people through out of turn. Being polite by breaking the order confuses everyone else waiting.
• Stopping past the line. Stop behind the white stop line. If there's no line, stop before the crosswalk.
• Creeping while waiting. Inching forward signals that you're going, which can trigger another driver to stop short.

Frequently asked questions

Who goes first at a 4-way stop if two cars arrive at the same time?

If you're on cross streets, the driver on the left yields to the driver on the right. If you're facing each other, both can go when your paths don't cross; if one is turning left, that driver yields.

Does straight go before left at a 4-way stop?

Yes. When two drivers facing each other stop at the same time, the one going straight (or turning right) goes first, and the left-turning driver waits.

What do you do when a traffic light is out?

Treat a dark signal like an all-way stop: come to a full stop, then take turns using first-to-stop and yield-to-the-right. Follow any officer directing traffic.
